Armando, you can assign a numerical value to each checkbox. Then using JavaScript you can perform calculations to add up the total amount along with the total of copies needed. We are doing something similar with School Transcript Requests. Depending on how many copies of their transcripts they are wanting along with if they want rush or standard priority. As Devin mentioned though, depending on how many options you have for them to choose from it may be easier to have a database hold those values. Especially if you have other forms that would use the same information.
